browning is the most serious problem for fresh-cut lotus root during processing and storage, limiting the shelf life of lotus root slices ( Conesa et al., 2007 ; Francis et al., 2012 ; Hodges and Toivonen, 2008 ). Phenylalanine ammonia lyase (PAL

`Fuji' apples (Malus domestica Borkh.) were harvested at three maturities for three consecutive seasons. Fruit firmness, soluble solids concentration, starch—iodine index (SI), and internal ethylene concentration were measured at harvest. Fruit were stored in 0 °C air storage for 8 months. Fruit firmness and other maturity indices were measured monthly during storage. Using a stepwise regression procedure, harvest maturity indices were used to predict firmness after air storage. When all maturity indices measured were represented in the model, R 2 = 0.29, 0.34, and 0.26 at 4, 6, and 8 months, respectively. Use of only SI and fruit firmness in the model gave R 2 values of 0.25, 0.29, and 0.24 for 4, 6, and 8 months, respectively. Although R 2 values were low, they were highly significant. The model using fruit firmness and SI resulted in the best fit. Thus, an equation was developed using months of air storage, firmness, and SI at harvest. Actual firmness values correlated fairly well with predicted firmness values, usually within ≈5 N. On Washington apples, predicted values were 4.3 and 3.7 N too low compared to actual firmness values after 3 or 5 months' storage. In 1993, when predicted and actual firmness values were compared for Pennsylvania apples, predicted values ranged from 2.6 to 8.3 N too high after 3 months' storage, depending on harvest date. In 1994, Pennsylvania fruit stored 4 months had predicted values 0.5 N too high to 6.3 N too low, depending on harvest date. It may be possible to develop and refine models for an apple variety that would be applicable to several regions.

Fourier transform infrared (FTIR) spectroscopy detected early large increases in fluid leakage from zucchini squash (Cucurbita pepo L.) subjected to a chilling temperature (5C). The increase in fluid leakage (principally water) was found after 1 day at 5C, while surface pitting was detected only after 3 days of storage at 5C. Prestorage temperature conditioning at 15C for 2 days greatly diminished the fluid leakage measured by FTIR spectroscopy after 1 day of storage at 5C. Measuring fluid leakage using FTIR spectroscopy seems to be a promising technique to detect the early onset of chilling injury.

MeBr fumigation of `Anjou' pears reduced external skin color values and increased the incidence of scald whether applied immediately after harvest or after 5 months of controlled-atmosphere (CA) storage. MeBr treatment did not influence external color of `Bosc' pears (Pyrus communis L.). Internal discoloration of `Bosc' pears was apparent only in fruit from CA storage and those that were not in good physiological condition before fumigation. Internal discoloration was apparent by either objective or subjective procedures. Firmness values of `Bosc' pears increased with MeBr fumigation and treated pears softened as readily as nonfumigated pears. Reaction of these winter pears to MeBr fumigation was not dose-dependent. Chemical name used: methylbromide (MeBr).
